High-Performance ZDS-3311 Pink Silicone Surface Filler
The ZDS-3311 Pink Silicone-based adhesive is a premium liquid filling solution specifically formulated for surface filling applications requiring excellent flexibility, fast light-initiated curing, and strong adhesion. This product takes advantage of silicone’s superior resistance to temperature extremes and excellent electrical insulation, making it suitable for sealing and potting sensitive components. Its vivid pink appearance allows for easy visual identification during application and quality control.
- Superior flexibility combined with an optimal hardness of 55A makes it resistant to vibration and mechanical stress.
- Fast curing with a 50W LED light at 365/395nm, delivering rapid production throughput due to a curing energy requirement of 500mJ.
- Medium viscosity (500 cps) allows precise filling of gaps, seams, or irregular surfaces without unwanted spread or run-off.
- The silicone chemistry is inherently resistant to moisture, many chemicals, and ultraviolet (UV) aging, ensuring long-term durability in harsh environments.
- Ideal for the electronics industry for surface potting, filling, conformal coating, or encapsulating electronic and electrical components, but also versatile for other industrial or craft sealing applications.
Key Applications
- Filling and sealing in electronic or electrical assemblies
- Potting delicate components for protection against moisture and dust
- Surface leveling or gap filling in high-visibility aesthetic projects where color-coding is important
- Fabrication, repair, and assembly scenarios in automotive, marine, construction, or DIY projects
Ensure you use appropriate curing conditions for optimum performance. ZDS-3311 Pink Silicone Filling Adhesive offers outstanding versatility for demanding modern manufacturing and repair applications.
